Referring more especially to Fig. 3, 1 in`I dlcates the framework ofthe machine supporting rollers 2 which coperate with rods 3 securedto a carriage truck 4 in which is mounted a platen frame or carrier comprising side portions 5 connected .by a cross rod` 6. -A platen ax1e'7 is journaled in the side portions 5 and a c lindrical rotary platenS axle. Journaled in the side portions 5 of the Vplatcn'frame or carrierl at the rear of the platen and about o posite its center is a rod 9 mounted upon w lch near its ends are depending hangers or arms 10 and 11 having ub portions 12 and 13 respectively (Fig:V 2) which surround the rod 9. Coiled s rlngs 14 surround the rod 9 outside thehu portions 12 and 13each of said coiled springs having 'one end .secured in one ofthe hub t portions and the other end secured in a worm wheel 15' (Fi 7), said worm wheel being Journaled on t e rod 9 and contained Within a case 16 secured by screws 17 to the ad]a cent side portion or bar 5 of the platen carrier.l As best ap ears in Fig. 8, a worm 18 having a screw E of the Worm wheel 15. It will be understood that' when said worm is turned by a tool properly applied to the head 19, the

worm wheel 15 isturned to increase or de-` crease the tension of its associate coiled spring 14, thereby increasing or decreasing the spring pressure applied to the associate arm or hanger 10 or 11. Two additional arms or links 20 (Fi 2 and 9) are loosely mounted vupon the ro' 9 betweenthe arms 10 and 11, one of said arms 20 being adjacent to each of said first described arms. The arms k20 depend from the rod' 9 and are provided at their lower ends with slots 21,'as

appears clearl in Fig. 9.- Asis also clearly s own sai' 11 is rovided at its lower end with a slot 11l w ich is preferably oppositely disposed Journaled'in the slotted lower-.ends of the vtwo arms 20 and the arms 10 and 11..is a main feed roller'shaft whichis clearly' shown in' Figs.2, 5 and 6. Said feed roller shaft tral portion 2 2an two end portions 23.

cad 19 is`]ournaled in each case 16 and coperates with the teeth-.

last named ligure, the armlthree portions," a cento the slot 21 in the adjacent arm 2O. Thek The central portion 22'i's'provided near its ends with bearing portions 24 which rest -in the slots 2l in the arms20and outsidel these bearing portions the central portion 22 is formed With a box or cup-like portion 25, one of these' portions 25 bein 'at each end of the main part 22v of the sha t. -The main portion 22 of the. feed I 'o'ller shaft has secured upon it the main art 26 of the paper feed roller, 'said feed ro ler surrounding the shaft and being adapted to turn therewith.

Each of the end portions 23 of" the feed v roller shaft carries an end part 27 of the feed roller at its outer end an'd is provided with a. bearing portion L28 and a cup-like portion 29, the latterportion'being at the inner end of the end portion or section 23. One of the bearing portions'28 is seated Within the slot 11 in the arm 11 and the otherbearing portion 28 is seated Within the slot A10a in the hanger Win10, The cup portion 2 9 of each end section 23 .of the feed rollershaft is close to one of the cup portions 25 'of the main part or section 22 .of said shaft and the openings in said cup por tions are in line with each other forming practlcally a smgle box-like receptacle with- 1n which is contained a double headed link 30 (Fig. '6). The heads 31 of said link 30 are provided withholes which are at rightangles to eachother and which receive head-y edpins,` pivots or rivets 32. The pins 32 ass loosel through the openings in the iieads 31 o the link and one of said pins is `secured in the walls of the cup1ike portion 25, whilev the other ofv said pins is secured in the walls of the portion 29. The con struction is such as to rovidea universal or gimbal -oint enabling t eend portions or sections of the feed roller shaft'to be moved l independently of the main section of said `-sha.ft in anydirection'transversely thereof,

thou y pellengi the main and end sections are comto turn together. The 'central section of said shaft and the end portions connected thereto by universal joints provide in effect' a flexible shaft upon which thev feed mounted and coperate with the platen in a manner presently to be described.

, roller sections `or portions, which go to make Yup the complete paperv feed -roller,` are A rod 33 extends from one of the arms 2() Ito the other of'said arms andsaid rod is secured tof'said arms between their ends. A paper-table the v.central portion of vits loweretidfhooked or eurledaround the rod 33, (Fig. 3) said paper table extending upWa-rdl and rearwardly from said yrod and a apted to be swung' about said rod as a ivot.v A short; distance above its hook or curled lower edge, the paper ta! ble 3 4`ex'tends `outwardly toward the sides fof the machine, as'indicateda-t- 34* (Fig. Q.

A feed rollv release rod 3 5 passes through and is secured th'e arms '20 in the arms 10 and 11, and 'the left'vv end portion of said release rod, asv 'appears clearly in Fig. fl, .is bent V'forwardly.andJ

towardthe left, its end entering 'gand'j be ing loosely seated in a perforation m a'.

. feed roll release lever 36' which is journaled .on the rod 6 which forms part' of the"platen carrier or frame. The construction is such that when the release lever 36 is'pressed. Y

rearwardly )it acts on the main' feed rollv through the release rod 35 and thearms 2O to move said feed roll away from the platen againstA the pressure of the coiled sprin s 14. The main feed roll 26 is` constanty pressed toward the platen by the springs let actingthreugh the hanger arms l0 and l1 on the exible shaft 22, 23. f

A paper apron 37 extends forwardly beneath the platen from tliecentral portion of the main feed roll, said paper apron conforming to the curve of the platen and be-- ing provided at the sides of its rear portion with rearwardly and i-...upwardly extending ears 38 (Fig. 4), said ears being of substantially the same Widthtas the extensions 34'? of the paper table, Aidieir ends' being reduced in width somewhat 'als at 38a and curled or hooked around the relase'rod 9 beneath said extensions and between the ears l() and 20 (see Fig. 2) at one side and the ears 11 and 2O at the other side of the machine. A screw 39 passes through a hole in each of the hook portions of the paper apron and is 'A received in the rod 9.,`said screws serving to properly secure said paper apron to said rod. As will clearly appear from' an inspection of Figs. 3- ande, the paper, apron 37 and paper table 34 form a practically continuous surface, save where the central section or part of the main feed roll protrudes 1 between them to coperate 'with the platen.

The end portions or sections of the feed roll, it will be noted, are outside of the side edges of the paper apron and paper table and the feed-roller supporting arms or hangers and beneath. said paper table and paper apron.

Referring now to the vices at the front side of?) preferably comprise a pair of members for feeding, guiding and controlling the paper, commonly termed paper fingers, mounted on a support above the platen; although, of

aper feeding de. the platen, these course, it is to be understood that one only of said pa er fingers may be employed if desired, an that they may be differently mounted. Above the platen axle, the side portions ofthe frame are formed .with upwardly 'and rearwardly extending arms 5a, heist shown'in Fig. 3. Thev arms 5 are bored out s indicated 40 (Fig. 11') to reestre *semi ngsleeves' il which may be ro-v rated in said bearing openings 4G, but which are nor?. ally maintained in a fixed position by setscrews enter threaded open- 110 the rods cooperating with said arms all lie simmoin'gs in the arms 5* andthe ends of which coact with r circumferential lgrooves 43 formed insaid bearing sleeves... Thus, thebearings for the cylindrical end portions 46.

of`a rod 47 which extends from side to side A of the platen fraine or carrier above the platen. The ends of the cylindrical portions 46 are threaded and receive locking or check nuts 48--which abut the collar portions 44 of the bearing sleeves, and tend to prevent the side portions of the platen frame from being spread, bent orl otherwise distorted. CoiledV springs 49' surround the rtions 46 of the rod 47, each` of said coifed spri vs having one end secured to said rod and lflic rother end secured to the adjacent bearing sleeve 41. y i

The main portion of the rod 47 between the cylindricalend portions 46 is preferably square in cross-section and is adapted to receive one or more paper fingers, designated asa whole by the reference numeral 50-and' comprising, as clearly appears in Fig. 10, a hub-like Vportion 51, an actuatin finger piece 52, an arm .53 off-set inward y from the carrying. arm or support 53lv and provided near its innerv end with av guiding portion 54, and also with a shaft bearing portion55 and-contactportions 56. The hub i portion 51 of the paper finger has its rear side open and is cut out to fit over or embrace the square rod or bar 47, being substantially C-shaped in cross-section. The

` outer end of the opening in the hub-like portion is counter-bored cylindrically so that the paper finger may be slid outwardly over the spring 49, as f'ar as the arm 5fi of the platen frame, without being obstructed by said spring. The hub portion is provided at its rear edges with. rearwardly extending lugs 57 which receive a screw 57a which extends across the -opeuing or slot in the rear side of said hub-like portion and prevents the accidental detachment of the paper finger after it' has been .properly mounted onl the bar 47. The bearing portion 55 near the-end of the off-set arm 53 of the paper fingeris slotted near its lower end, as indicated at 58 (Fig. 3), and bearing in said slot is a. feed roll shaft 59. A screw 60 extends across the open mouth of and thus closes the slot 58 after the feed roll shaft ment.

is ai place. The feed m11 shaft 5al has-feeaf rolls 61 and 62 fixed on it, one at each side of the bearing portion The shaft extends beyond or outside of said7 feed rolls so that its ends are adapted'fto coperate with the flat contact edges 56 Figs; 3f and 10) or the portions or lugs 56. achzof the feed rolls lies between and is partly embraced by one of the contact portions 56 and the bear'- 4in portion 55. -The vshaft 59 is loosely journa' ed in its bearing slot 58 in the portion 55 so that-it may oscillate or 'turn freely to ermitone or another of the feed= rolls to e moved toward or away from theplaten in a radial direction, but oscillatory move,- mentup and' down or in a direction tangential of the platen by said shaft and lfeed rolls is prevented by the contact edges of the portions 56 which latter lie above and it firm The operation of the devices above explained may be briefly outlined. The'paper n ers are first adjusted so that as the paper is ed around the platen the inner marginal feed rolls 61 only engage the paper, while the outer marginal feed rolls 62 wlllbe outside the edges of the paper and will remain in' contact with the platen. This arrangel-- ment will be understood from an inspection y againstsuchfup anddown moveof Fig. 11, wherein the paper is indicated b'y dot-te ines and is marked -with the reference character a. paper fingers along the support 47, said su o'rt is'turned or swung rearwardly in tllie euri sleeves 41 by rearward pressure exert municating rotary motion to the r' 47 against the ressure of its springs 49 and swinging bot paper fin ers upwardly so as to move the margin fev rollers 61 and 62 out of contact with the platen. In this po# sition the other of the two paperfingers may be slid-freely lengthwise of the rod 47 unt1l said paper finger is in''proper position, con'- sidered longitudinallyof the platen. `Thereupon rearward pressure is transferred to the adjusted paper fin-ger. and the first aper finger is then roperly adjusted longltudr nallyT of the p aten. As soon as rearward pressure against the finger port-ion 52 is re;

' moved the springs 49 swing the rod 47 vforwardly in its bearings until the feed rolls In order to ladjust the' 'against the actuating finger piece 52 of one'of the paper fingers, thereby comin the paperfin,f 1fers` Contact;` with .the platen with a pressure depending upon v'the tension of the sprin s 49. The tension of said' springs may e regulated by loosening the set screws 42 and then communicating rotaryA lmotion to thev bearing sleeves by' a turning tool inserted in the holes 45. lThe tnrnin of the bearing sleeves 43- Will serve to win or unwind the springs 49 until the proper degree of tension is obtained, whereupon the set screws 42 areftightenedto maintain the .paper a is introduced into the machine over-the paper table`34 and is guided by the latter down between the platen and the centr-al section 26 of the main feed roller, and is thence fed or line spaced 1in a'known manner vover the .paper a ron i'forwardly and upwardlyzbetween At ve laten and the feedrolls 61. It'will be note from an inspection of 'side edges '-of all ordinary widths of 4paper and will actas friction rolls, remaining at" lall times in 'contact with the surface of the platen when ordinary widths of paper are Figs., 2and 5 that the end vport-ions 27 of the main paper feedfr'oller are at the extreme ends of the platen; consequently the end portions 27 willbe outside of or beyondthe employed. ,The platen issomewhat wider thanthe length of any line 'that can be written upon it; (said line bein 1 ofh lesslength than the distance between 51e end portions 27 of the feed roller) so that there would be a waste in employlng paper of abnormal width. The universal joints connecting the end portions of the feed roll` shaft with the central portion of said shaft permit the central portion 26 of the feed roller to be moved away from the -platen as the paper is passed downwardly between them, whileatthe same timethe endl portions 27 of the feed roller are not Amoved away, but remain in direct Contact with the platen. This relanumber of sheets are to be entered and writtion of the `parts is' shown in Fig. 5 and vthe construction enables the feed roller toA be directly turned by the platen at all times and to beturned independently of the con* tact of the feed roller with the paper on the platen. A It' is of especial advantage whenl a ing work. Prior to my present invention ilV frequently occurred that the sheet nearest the platen would cling to the latter and be fed around while the outer sheet or sheets would be stopped when they cont-acted with the feed roller and would be held back so as to impair and change the correct and proper relative arrangement of' the sheets which, of' course, 4should be fed together in the relative arrangement in which they are introduced into the machine Furthermore, in such prior structures,v even after the plurality of sheets had been fed into the .machine-and over the feed roller, the latter, being-then completely separated from the platen, would' have 'no' direct connection or contact there with and therefore would not at all times turn'. The result would be; that while the sheet in contact with the platen and one or at the rear of the `:ia-chine.

more nearest to it would be fed around,

farther away from the laten would be held back, or, 1n other wor s, the sheets nearest farthest away, thereb iinpairingthe'correct arrangement of thfS ets."'- By"'1ny"-present invention the outefrp'otions'of th'nia'i'n' feed roller are'at all times in directen'gageinent or contact with the laten so that the central portion of said,4 f e' roll which engages the paper is frietionally driven by te platen and i's given rotary movement whenever the platen is given rotary movement no matter howmany thicknesses of paperv there may be I between said cent-ral" portion and-the 4plantent-1" The result is that/ a number of sheets may be readily entered `th, macliine/ and fed around the platen'without altering the; iniial relations ofgsaid/ sheets one to another.

When the paper has been line spaced or fed around with the platen b the psual mechanism until the leading e ge or edges pass between the inner feed rolls 61 and the platen, said feed rolls 61 are moved radially.

4of the platen and outl of gcontact therewith,

while the outer feed rolls 62 are at the same time forced intofstill closer contact -with said platen than they'norm'ally have. The

feed rolls 61 and 62 are fixed on'- thel feed roll shafts 59 and consequently the rot-ary movement of the platen is transmitted directly from the; outer jroll 624:0 the'inner roll 6l, thereby causing thea-.latter to properly feed the paper at all times, as described above in connectionwith the main feed roll The arms 5,3 of the paper fingers are brought downwardly `and forwardly over the platen so that the feed rolls carriedby said farms may be arranged as close to the printing line as possible, this' arrangement conduc ing to a smooth and even feed of the paper. After passing between the platen and the feed rolls on the 'paper fingers the paper passes upwardly and rearwardly, being guided by the guide portions 54 of said paper fingers and thence isfed out of the machine overV the supporting rod 47 and hence said supporting bar does not obstruct the, operators view of the writing. By olfsetting the margin feed roliers 6162 from the supporting arms 53 in the manner`described the said feed' rollers` may coperate with the-paper and the paper be directed over the supporting bar 47 -without interfer-` ence from the arms 53a or themeans which support the margin feed rollers? .As previously explained the feed rolls'on the paper fingers are prevented from movingiup and down or sli ng over the platen or the paper thereon by the 'goperation of the ends vof the feed roll shafts 59 with the lContact por tions 5il of said paper n ers, while the construction Ais such. thatsai 'shafts may to coperate with the paper'and the outer rolls to coperate with the platen.

The broad principles governing the operations ofmy improved main paper feed roller device and my improved paper finger device are similar in some respects, and I have preferred to show said devices as cooperating together in one and-the same machi-ne. It is to be understood, however, that one of said devices may be employed sepa- V rately and apart from the other, and, while I have shown one' construction for each of said devices, that. variousv changes may be made in the construction of the parts, in

their arrangementgand in their mode of operation without departing from the spirit and scope of my invention.
